Conversation
A varchar column could render as a boolean checkbox for the entire session because use-introspection cached the DB schema with staleTime: Infinity and refetchOnWindowFocus: false. If a column's type changed in the DB after Studio loaded, the editor never updated. Three fixes: 1. Refreshable introspection: drop staleTime: Infinity and enable refetchOnWindowFocus so the schema re-introspects when the user returns to Studio. Add a dedicated 'Refresh schema' toolbar button (Shadcn Button + Tooltip, DatabaseZap icon, loading/disabled state) next to the existing 'Refresh table' button in ActiveTableView. 2. Self-heal on type-mismatch write errors: when an insert/update fails with Postgres SQLSTATE 42804 (datatype_mismatch) or 22P02 (invalid_text_representation), invalidate the introspection query cache and refetch so the editor re-renders with the correct type. The original error is still surfaced; the self-heal only adds a background refetch. Hooked into the insert and both update error paths. Shared query key + helpers live in refresh-introspection.ts; Postgres error detection in postgres-core/postgres-error.ts. 3. Surface the DB type in the cell editor: wrap every dispatched editor in a ColumnTypeLabel (Shadcn Tooltip) showing 'type: <name>' so schema drift is visible instead of just producing a wrong widget. Architecture/introspection.md and cell-editing.md are updated to reflect the new fetch policy, self-heal contract, and type-label contract (the previous introspection doc mandated staleTime: Infinity, which this fix corrects). FEATURES.md documents the new capability. Tests cover the new behavior; typecheck, lint, tests, build, and check:exports all pass.

Summary by CodeRabbit
WalkthroughThe change adds PostgreSQL SQLSTATE classification and shared introspection refresh utilities. Introspection now refetches on window focus, supports manual toolbar refresh, and refreshes after PostgreSQL type-mismatch write errors while preserving the original error. Insert and row-update hooks use this recovery path. Cell editors now display formatted database column types through Merge Risk: 🔵 Low · up to The PR improves schema refresh and makes database types visible in the editor. It is mergeable with owner follow-up because screen-reader users may not receive complete array and nullable column information from the new type label, and the related architecture wording should be clarified. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Comment |
PR #1567 removed staleTime entirely, so react-query defaulted it to 0. That caused a full DB re-introspection on every component mount and every window focus. Set staleTime: 30_000 so the cached introspection stays fresh for 30 seconds, while keeping refetchOnWindowFocus: true so window-focus refetches still refresh the schema after the stale window.

Remove tabIndex={-1} from the native button in ColumnTypeLabel so it
remains reachable via normal keyboard navigation. Tooltip and styling
behavior are unchanged. Addresses CodeRabbit review on PR #1567.
…d label focus Four corrections to PR #1567 after CodeRabbit review: - use-introspection: change refetchOnWindowFocus from `true` to `"always"`. React Query v5 treats plain `true` as "refetch only stale queries", so the focus-refetch test failed while data was fresh; `"always"` bypasses staleness on focus. The 30s staleTime is kept. The comment block above the options now documents the 30s-throttle + "always" focus-refetch policy. - use-introspection.test: update the stale comment that said "The fix drops staleTime…" to describe the real 30s-throttle + "always" behavior. No test logic changes. - Architecture/introspection.md: reconcile the Fetch Policy Contract, Refreshable Schema Contract, and Testing Requirements sections with the code (refetchOnWindowFocus: "always", staleTime: 30_000). - ColumnTypeLabel: revert the removal of tabIndex={-1} from the tooltip button. PopoverCellContent does not override onOpenAutoFocus and no editor input uses autoFocus, so Radix focuses the first tabbable element when the cell editor opens; without tabIndex={-1} the label steals focus from the editor input on every edit. A comment notes this is intentional so it is not removed again. typecheck, lint, and the introspection hook tests all pass.

Clarify the shared refresh mechanism contract.
The window-focus path does not call refreshIntrospection; it uses React Query's built-in refetchOnWindowFocus behavior. State that manual refresh and write-error recovery use the shared helper, while window focus uses the query policy directly. This prevents the architecture document from implying that changes to refresh-introspection.ts also control focus refetching.
Proposed wording
-- window-focus refetch (React Query built-in, enabled by `refetchOnWindowFocus: "always"` + `staleTime: 30_000`).
+- window-focus refetch (React Query built-in, enabled by `refetchOnWindowFocus: "always"` + `staleTime: 30_000`; this path does not call `refreshIntrospection`).📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Problem
A
varcharcolumn could render as a boolean checkbox for the entire Studio session. Root cause:use-introspectioncached the DB schema withstaleTime: InfinityandrefetchOnWindowFocus: false, so if a column's type changed in the DB (e.g. boolean → varchar) after Studio loaded, the editor never updated and stayed wrong for the whole session.Fix
Three changes, in order of impact:
1. Refreshable introspection
staleTime: Infinityand enabledrefetchOnWindowFocus: trueinui/hooks/use-introspection.ts, so the schema re-introspects when the user returns to Studio.Button+Tooltip,DatabaseZapicon,aria-label, loading/disabled state bound toisIntrospectionRefetching) next to the existing Refresh table button inActiveTableView.refreshIntrospection,selfHealOnWriteError) live in the newui/hooks/refresh-introspection.ts.2. Self-heal on type-mismatch write errors
42804(datatype_mismatch) or22P02(invalid_text_representation), the introspection query cache is invalidated and a refetch is triggered, so the editor re-renders with the correct type.use-active-table-insert.ts) and both update error branches (use-active-table-rows-collection.ts). Postgres error detection lives in the newdata/postgres-core/postgres-error.ts.3. Surface the introspected DB type in the cell editor
ColumnTypeLabel(ShadcnTooltip) showingtype: <name>(plus a nullable hint) inside the cell popover, so schema drift is visible instead of silently producing a wrong widget. Type string comes from the existing Postgres catalog→SQL-alias mapping.Docs
Architecture/introspection.mdupdated: the previous Fetch Policy Contract mandatedstaleTime: Infinity+refetchOnWindowFocus: false, which directly conflicted with this fix; corrected per AGENTS.md. Added Refreshable Schema, Self-Heal, and Cell Editor Type Label contracts.Architecture/cell-editing.mdupdated: Input Type Dispatch Contract now requiresColumnTypeLabelwrapping.FEATURES.mddocuments the new capability (Refreshable Schema, Self-Healing Editor on Type-Mismatch Write Errors, Cell Editor DB Type Label) and updates the existing Live Introspection / Introspection Recovery entries.Tests
Bug reproduced first in
use-introspection.test.tsx("re-introspects when the window regains focus"), then fixed. New tests:postgres-error.test.ts(8),ColumnTypeLabel.test.tsx(6),use-active-table-insert.test.tsx(2), plus additions touse-introspection.test.tsxanduse-active-table-rows-collection.test.tsx.
